Default Rear Wheel Bearings

Is anyone else running Darkside wearing their rear wheel bearings out quicker than MT tire runners?

I have right at 52000 on a 2013 RGU and have wobble from the rear. I figure its the wheel bearings or maybe the swing arm bearings?

Has nothing to do with running a car tire, you are lucky to get that many miles out of the stock bearings, they are packed with very minimal amount of lube. You don't mention if you have ABS but it's my guess you don't, the ABS bearings don't have the failure rate as much as the standard 9276A's. The stock bearing will last much longer if you remove the rubber seal and pack with a good quality wheel grease, easy to do, or go with an after market, they can be cross referenced to a brand of your liking but Timkin under the name Fafnir also makes. Also make sure you replace the front also while you are at it, I know of many failures at half your mileage. Stay on the dark side if you prefer, regardless of what you hear or are told by a hater it has nothing to do with short bearing life. Hope this helps.https://www.hdforums.com/forum/dyna-...el-wobble.html

Thank rlh7677.

I do have ABS.

I have checked the front bearing and they are still good. Didn't change them at this time per recommendation of one of the local Indy shops but may still once I get this issue resolved.

The ABS bearings have not been failing like the non ABS . You can easily check the front bearings by removing the rubber seal, if they are dry or you have any doubts then change them or if you need a front tire soon then just catch them then. If you ride local it's no big deal, they will give you plenty of warning to change them but if you travel then don't take the chance to have to spend a day at a dealer. Good luck !

The rear wheel bearing on my '15 **** the bed in just over a year. The most experienced tech I know and respect said it's common. Front wheel bearing was replaced at 22 months.

It's probably not your CT.

When you get new bearings, as previously said pop a seal and check them, and if they have what looks like clear vaseline (I've seen a lot of this), clean all that junk out and regrease with a premium name brand synthetic, not the buck.99 house brands. Even if it's $10 a tube or more, that does a lot of bearings. I also toss any wheel bearing with plastic ball spacers, only use bearings with sturdy metal ball cages. I've pulled the plastic types with ground up plastic in the grease. I think the major problem with premature wheel bearing failures is grease, not good enough or enough of it. I only use American brand bearings, though I haven't been able to find some Harley sizes from them and tried AllBalls. Those are Chinese, but evidently a whole lot better (cheaper, too) than Harley's Chinese bearings, with double seals on each side, sturdy metal ball cages, well packed with Chevron synthetic grease, and they have ABS replacements, too. Too bad there aren't any Timkin tapered roller bearing conversions, they just didn't fail if you greased and installed them right.
